That is not what the schematic indicates. 6K7 G3 is the Suppressor grid on pin 5 which is normally attached to the Cathode. In this case, according to the schematic, there is supposed to be a small negative bias from the power supply in addition to the AVC circuit. That grid is also connected to the other 6K7 rf Amp Suppressor grid. The only connections to an IF transformer for the 6K7 IF tube is the grid cap and the plate, pin 3.

So, is it possible that Ron Ramirez yellow wire from 6K7 pin 5 goes to the other 6K7 pin 5?
